In this lesson, you will learn about the architecture of Java servers and the essential files involved in setting up a servlet environment. You will be guided through integrating the OpenEdge Web Services Adapter (WSA) into the Java Servlet Engine (JSE), configuring security access for the WSA, and discussing various security options for your web application. The lesson also outlines the phases of setting up servers, building a 4GL application, and deploying web services. By the end, you will have a fundamental understanding of the deployment architecture and configuration files necessary for successful integration.
